*** These straps work for both the original and the Xtreme model Heater Body Suit. Need a new carrying strap? Not a problem, the new carrying straps feature a three-piece system for a more comfortable carry and are easier to use. The new design has detachable shoulder straps. This makes it nice if you use a backpack to carry your Heater Body Suit. You can also detach one side of a shoulder strap and wrap it around a tree or tree stand to hold your suit if you are not wearing it. Please Note: All Heater Body Suits come with carrying straps; these are simply replacement straps if yours have been lost, misplaced, or have broken. The carrying straps work with both versions, the original and the new Xtreme.
